We develop new measurement and analysis methods for neutron Talbot-Lau interferometry at "RADEN" in J-PARC MLF by mainly utilizing property of pulsed beams for precise and efficient imaging. As high-precision processing technique for grating fabrication, imprinting method of metallic glass was adopted, and achieved an analyzer grating which works in the wide wavelength range. These techniques will also promote the widespread use of Talbot-Lau interferometry even at compact neutron sources.
